HBASE-12247 Replace setHTable() with initializeTable() in TableInputFormat. (Solomon Duskis)

Online config change
...
Summary: This diff is intended to forward port HBASE-8805 and HBASE-8544 implemented by Gaurav Menghani in 89-fb. This improves operational efficiency in managing clusters that are serving production traffic. The idea is to have a central configuration which can manage notifying the configuration observers. The observers in turn should update their local state from the latest config. Minor caveats where configuration variables are corelated should be taken care of with additional care.
Test Plan: Unit tests

- if (completed == null) tasks.wait();
+ while (completed == null) tasks.wait();

half-ways previously.

and it can trap meta on the most loaded server in the cluster.

When hbase.block.data.cachecompressed=true, DATA (and ENCODED_DATA) blocks are
cached in the BlockCache in their on-disk format. This is different from the
default behavior, which decompresses and decrypts a block before caching.
